Detailed Recommendations for I-OnAsia New York

Risk Advisory

"I have retained I-OnAsia on a case-by-case basis for high level business intelligence, asset identification and investigative due diligence throughout Asia and Latin America for more than 10 years. During that time period, I have developed a very strong relationship with I-OnAsia and specifically, James Tunkey. I find the work consistently solid, delivered in a timely basis and with the utmost integrity."

Fraud Investigations

"James Tunkey supported asset searches and undertook investigative work in support of litigation involving recovery of very large sums.  James and his team also undertook an asset search, involving a target with more than USD1 billion in net worth. That particular search was global, across the US, Europe and S-E Asia in particular. I was very pleased with James' work, which lead to significant recovery."

Due Diligence

"I have been happy to work with I-OnAsia on numerous occasions. From conventional counterpart credit risk assessments and more detailed background searches on larger investment targets that required access to public and non-public sources of information to far more complex and sensitive investigations of counterparties defaulting on their obligations under contracts with my company. I have throughout been impressed by I-OnAsia's discretion and ability to secure actionable information.  James Tunkey's intelligence has been used in dispute resolution and recovery of unpaid debts of significant size."

Litigation Support

"James Tunkey and the firm of I-OnAsia assisted my office by conducting a complex search. The search involved sifting through a great many documents, and undercover interviews of executives. The targets had conspired to transfer assets, made false statements, and Tunkey's team gathered key evidence that was used to pursue legal redress and recovery. Tunkey had been referred by a colleague at a major financial institution and his work performance met high expectations."
